The tools of optogenetics, which are transforming neuroscience, were used to locate and chemically label neurons, as well as make them susceptible to activation by blue light transmitted by a fiber optic cable. With these techniques the researchers were able to identify and label which neurons were involved in forming the initial memory of the first environment, and to reactivate the labeled cells a day later with light. Dr. Tonegawa said that because the mechanisms of memory formation are almost certainly similar in mice and humans, part of the importance of the research is “to make people realize even more than before how unreliable human memory is,” particularly in criminal cases when so much is at stake. That unreliability, he said, prompts a question about evolution: “Why is our brain made in such a way that we form false memories?” No one knows, he said, but he wonders if it has to do with the creativity that allows humans to envision possible events and combinations of real and imagined events in great detail. That rich internal experience fuels work in the arts and sciences and other creative activities, he said. “Unless you have that kind of ability, there is no civilization,” he said. But it could also provide raw material for false memories — a possible “tradeoff for this tremendous benefit. — Scientists Trace Memories of Things That Never Happened - NYTimes.com

Dear George Zimmerman,
For the rest of your life you are now going to feel what its like to be a black man in America.
You will feel people stare at you. Judging you for what you think are unfair reasons. You will lose out on getting jobs for something you feel is outside of your control. You will believe yourself to be an upstanding citizen and wonder why people choose to not see that.
People will cross the street when they see you coming. They will call you hurtful names. It will drive you so insane some days that you’ll want to scream at the top of your lungs. But you will have to wake up the next day, put on firm look and push through life.
I bet you never thought that by shooting a black male you’d end up inheriting all of his struggles.
Enjoy your “freedom.”

We grew up with a model, and set of assumptions, that proved untrue. During our childhoods, unemployment was low, houses gained in value, a bachelor’s degree left you prepared for a variety of employment opportunities and investing was a sound decision. Now all of those things aren’t the case. It’s our job to deal with that, and that’s fine. Generations have faced much worse. But it’s easy to distrust a system that melted down so spectacularly just as it was time for us to buy into it. — A Very Gentle PSA To Anyone Writing a Trend Piece about Millennials
